Groningen students build world’s largest touch screen

Filed under: Gadgets,IT,Technology by Branko Collin @ 5:12 pm

Writes the High Perfomance Computing and Visualisation department of the University of Groningen:

Scientists can now use our new enormous multitouch screen. […] We turned our existing 3D theatre with a big cylindrical screen into one that can detect 100+ simultaneous touches. We mostly used off-the-shelf hardware components and public domain software. Apparently size does matter and the result is really impressive.

[…]

Now we have such a touch screen we can use it for driving our existing software, but the initial goal was to facilitate the scientists studying Geographic Information Systems and a research group that studies interaction methods for touch screens. Having such a huge screen changes the way people interact with data and with each other. They could easily work on part of the screen in their own little environment but could switch very fast to a more collaborative approach.

University cracks Internet security of the future

Binary code

Researchers of the Eindhoven University of Technology have managed to crack the McEliece cryptosystem. This system is a candidate for securing Internet traffic in the ‘Post-Quantum Computing’ era, when the superfast computers of the future will be in use. The scientists presented the crack as well as a new encryption key.

Last weekend’s successful attack was done using a large number of computers linked together throughout the world, explained Eindhoven University of Technology professor Tanja Lange. Together with her student Christiane Peters they presented a new encryption key with which the McEliece code will be immune to quantum computers.

Banks currently use the RSA code from 1977 to secure electronic transactions. A quantum computer would have little problems cracking this code, something that takes an ordinary computer three weeks. This is why researchers are looking for something better now before the introduction of quantum computers, which according to Lange is another 10 years away.

How to tell ultra-portables have arrived

Filed under: IT by Branko Collin @ 9:52 pm

This is the front page of this week’s issue of a DIY chain’s product folder. When DIY stores start not just selling computers, but ultra-portables at that, you know that ultra-portables have arrived.

For the non-geeks among us: ultra-portables are light-weight, small notebooks, suited for web browsing and word processing. Medion is a company that sells computers through supermarket chains such as Aldi, and apparently also through DIY stores. For the geeks among us: Medion Akyoa Mini, Intel Atom 1.6 GHz, 1GB RAM, 80 GB HD, 10″, 1.2 KG, webcam, microphone, Windows XP, 802-11n. (Apparently this is the MSI Wind.)

Keep track of your cat with GPS

Filed under: Animals,Gadgets,General,IT by Orangemaster @ 9:12 am

An electronics company in Hengelo has developed a GPS system for tracking cats, which it will launch sometime this fall. The goal was to reduce the amount of abused cats: Wilfried Peezenkamp thought up the system after his own three cats came home in a bad state.

The cat gets a small GPS receiver in its collar. By coupling a base station to a home computer, users can see using the digital atlas Google Earth where their feline friend is. “If the cat is trapped somwhere because its paw is stuck, then you can take action right away,” says Peezenkamp.

I’m wondering how original this idea is. The famous Mr Lee cat of the Mr Lee’s cat cam already has a CatTracker for sale, a – you guessed it – GPS tracking system that looks exactly the same as what this company is suggesting (picture shown here).

Oh nose, more hyperrealistic papercraft

Heerlen-born, Rotterdam-based artist Bert Simons makes these scarily realistic papercraft models, by first making 3D models of real subjects. Playing with the uncanny valley, eh? Dude uses Free Software, namely the 3D package Blender (originally from Dutch company Not a Number, but released as GPL software after a donation drive); and Ubuntu for his web server.

Electrowetting displays coming up in 2008

Filed under: Gadgets,IT by Branko Collin @ 8:30 am

Philips spin-off Liquavista announced last week that it will start production of so-called electrowetting displays this year, having secured 8 million euro in investment money. Electrowetting is a member of a loosely knit family of energy efficient reflective display technologies. It works by manipulating layers of oil and water in a cell (pixel). Liquavista expects to produce small displays for use in mobile devices such as mobile phones and watches first. The Eindhoven-based company claims its ColorMatch FreeStyle platform will have more than twice the brightness of LCD displays.

The Netherlands is sloppy at protecting privacy

Filed under: General,IT by Orangemaster @ 1:42 pm
privacy

The Netherlands scores a poor 21st place on the international list of countries that uphold citizens’ privacy, according to the 2007 International Privacy Ranking of Great Britain. The Netherlands is in the category labelled “systematic failure to uphold safeguards” when it comes to privacy. The Netherlands also scores poorly when it comes to ID cards and biometrics.

According to Privacy International, the Netherlands’ score is so bad because of its compulsory identification, the possibility of listening in on phone conversations (communication interception) and the obligation of storing Internet data (data sharing). If you read the section entitled ‘countries with the worse records’, the Netherlands gets nailed for its leadership, albeit along with half the EU and others.

Some highlights of the privacy problems specific to the Netherlands:

– Continued proposals to increase power of law enforcement agencies
– Plans to implement in 2008 a database of all children to record development from birth
– Compulsory identification for all persons from age of 14, where 5,300 individuals are fined every month for not carrying ID
– Courts have ruled that subscriber data can be disclosed to copyright industry, and anonymous website owners

Government axes electronic voting

Filed under: IT by Branko Collin @ 9:48 am

Last week Minister of the Interior, Bijleveld announced (Dutch) that for now the Netherlands will return to paper voting. A committee headed by former minister Korthals-Altes had concluded that currently electronic voting systems are unsafe. Earlier, the Wij Vertrouwen Stemcomputers Niet group (We do not trust voting kiosks), headed by well-known hacker Rop Gongrijp, had demonstrated how easy it is to hack a voting kiosk without leaving a trace.

The Korthals-Altes committee concluded that electronic voting should leave a paper trail, so that votes can be re-counted if necessary, and that it should be transparent. The soonest moment at which electronic voting can be re-introduced would be after the 2009 elections for the European parliament.

Caving your trolls

Filed under: IT by Orangemaster @ 10:32 am

A new Dutch plug-in for the blog software WordPress fights trolls in a very Dutch way. This week, Henk Van Ess of Voelspriet.nl launched the Cave Your Trolls concept. The idea of Cave Your Trolls is to let “bullies” in forums and weblogs keep doing what they do, without anybody reading what they spew. Instead of moderators having to remove their nasty comments manullay, the trolls sit in their cave and keep talking to the walls. WordPress users can now download the beta version.

Digital RIP first

Filed under: Dutch first,General,IT by Orangemaster @ 10:12 am

As of this Wedsnesday, cemetery de Larikshof in Rhenen, Utrecht is the first to boast a digital headstone complete with screen, which can show films or slides. However, visitors of de Larikshof need a special battery to activate the screen. And of course, the films and slides are hopefully related to the dearly departed.
